very nice craftsmanship! Would 45 degreeing the corners taken too much port space? HOw do you calculate the port area with those flares! lol

That's really 3.2 cubes after port area? Looks really small.

This was my first flare port so I havent got it all figured out yet. I will probly 45 the inside corner of the port that isnt rounded. I guess I will keep learning as I build more. Thanks for the suggestions fellas

the 45's are there to help maintain the same port area through a bend, namely the width. I would have definately put a couple in there.

I draw them up on sketchup to see what the appropriate size would be..To maintain desired port width.

Box looks good tho.

You will love life, after you do.

It looks like you cut the hole w/a steak knife.. :laugh:

Yeah it was decent til I tried to use the router to smooth it out and I fu<ked it up. Had to sand it all out and redo it.

Lol word. I really need to get a jasper jig

Make your own. It's not hard and can be done with some 1/8" mdf or similar type of wood. Just cut out a hole for the bit to pass through and then mount it with screws from underneath. To get the cutout radius, use a square and place the bit in the inside corner and measure out. This gives you the distance to the center from the outside of the bit. It works the same way as a jasper jig and as you make more an more circles, just label the centers for the radius you cut out. Over time, you will basically have your own jig for about $3.

You can also make a template to use over and over.

Thanks man! I have some lexan glass laying around so I might try to make one out of that.

That would be even better than using wood!

You should see my ghetto *** jig I have!I made it out of a parking sign (1/16 in steel) and works like a dream.Don't spend the money on a jasper jig.Once you make a few rings you'll get the sizes you need and if you need more just add.Make sure to mark what each hole cuts like "inner dia. or outer dia."

lol you should see mine right now. Its a make shift compass made from 2 pieces of mdf screwed together with a nail and a pencil duct tape to the end of the wood. And thanks for the tips!

You guys know where I can learn about how to do a horn design?

JLJunkieMX107

I got the design for a t-line laid out. 90.6 inches in length, 80 in^2 port area. Dimensions of the box are 22.5"w x 20"l x 16"h . Port is 16" x 5". The port will have 4 folds. Just by these figures does it seem right?

This is for a single 12 with an FS of 37.4

Did you let flakko cut the hole for you?

LOL, someone dig up that pic...

Anywho, I dont know about assembling the back port like that. Should have just made the port it 2 pieces, instead of 3.

lol i love that flakko pic

And the kerfing is nice, but i most definitely wouldve kerfed that second bend. How much volume is it, and whats it tuned to?

LMFAO that pic just made me feel a whole lot better about my cut. It actually wasnt that bad til a tried to use the router to smooth it out and fuxored it up. I dropped a MAW 15 in it today and pushed it with 125 watts and it beat pretty hard. Once the full 500 watts is pumped into it, it should be wangin.

Thanks for all the tips and suggestions. This was my first flare box so now I know how to make the next box better. Thanks fellas.

Not a bad box...

Only trying to give constructive criticism...

The two kerfed corners are negated by having the 90* corner in the middle of the port.
